Application filed February 18. 1907. Serial No. 357.976-

TO all whom it may concern:

Be it known that we, LEON A. FLiNKnR and J OHN SCHADE, Jr., citizens ofthe United States, the said Lnoa A. FLiNKER residing at the city of NewYork, borough of Manhattan, county and State of' New York, and the saidJOHN SCHADE, Jr., residing at the city of New York, borough of Brooklyn,county of Kings, and State of New Yorlgfliavev invented a new and usefulCutlery-Sharpening Machine, of which the following is a specification. l

Our invention is a machine f or sharpening cutlery, the same 'heiligadapted for sharpening the blades of all kinds of razors, includingordinary razor blades, the

short safety-razor blades having one cutting edge, of wcll-knownconstruction, and, also, the thin blades such as are use'd in the"GilletteW type of safetyrazors. I

ln Our machine a razor blade of any kind may be i introduced orWithdrawn` easily and quickly."ln sharpening safety-razor blades, weemploy an auxiliary holder adapted to receive and retain the blade,

said parts being introducedinto a main holder whichlis :so operated asto present the edge of the blade to a strap in such a manner as tothoroughly sharpen it, and, in the caso of the double-edged safety, tosharpen both edges` thereof.

The machine is adapted to be .opened for obtaining access to the mainblade-holder, and, when so: opened, the several parts are locked andheld securely against slipping` thus enabling the Operator lto insertand withdraw a blade without danger of being accidentally cut by theblade. i

After the 'blade is introduced into the main holder, it can be forced oradjusted edgewise in order to wedge the blade firmly into the holder andprevent it from slipping. This adjustment may be used in connection withan auxiliary holder and a safoty-razor-blade, for

the reason that said blade may be clamped tightly in the auxiliaryholder which is in turn wedged in the main holder.

The sharpening strop is so guided in the machine that a pull in onedirection or the` other on said strop tends to keep certain side membersof the machine in closed positions, thus insuring a proper relation ofthe strop to the razor blade in the holder. Means is provided wherebysaid side members may, it' desired, be securely locked into operativoposition independently of the strop.

In th'e accompanying drawing we have shown one embodiment of theinvention, but the-construction shown therein is to` be understood asillustrative only, and not as defining the limits ot `the invention...

Fig. 8 is a cross section similar to' Fig. 7, showing adouble- 75 edged safety razor bladev of 'the` Gillette type-held in saidauxiliary holder. Fig. 9 is a cross section ou the lineI 9 9, of Fig. 6,showing an ordinary short blade of a safety razor'attached to theauxiliary holder. Figs. 10,-.-11, l2 and lvarc detail views showingvarious 80 means whereby either of the strop guiding rollers, proferablythose at the outer ends o f the pivoted side members may 'be adjustedwith relation to the path ol movement of Ithe strop. A f

The supporting frame for the working parts of our machine is 'shown bythe drawings as consisting of a supporting or back member A and aplurality of guide supporting membersB C each ol' which is precrablyTmade of sheet metal although said members may be of cast metal -iidesired. The supporting or back me1u- 9p her A is shdwn as consistingola. plate which is provided -at its end portions with lugs cz a extendingpreierably at right angles to'said plate. The'plato is provided at aboutits middle with slots a in which is titled the bight or loop loi ananchor strap D whereby the machine may be' connected to a suitable xiured. 'such as a bracket or hook which is attached to a wall or othersurface ior the purpose of loosely anchoring the machine when it desiredto use the same for 'slropping or strapping a razor blade. We do not de-100 sire to limit ourselves to the particular' means for 'liold-V ing oranchoring the machine when in use. but the strap D affords a convenientmeans for this purpose,

and it may also be adjusted around the .machine when the parts thereofare folded for storage or 'transporta- 105 tion.

.The members B C are shown as consisting Oi, flat plates, whichhr'eprovided on their respective edges with flanges b c. The flanges at oneend oi the res. speetive plates are extended to form arms b s, which 119ser wl. inwfirtlly from the pluies oi said members, and led to bebrought into overlapping engagement .ne sind lugs a a oi the back orsupporting member ie side flanges I1 c oi; the members B C are also edinwardly at the other ends to i'orm the short ell as clearly shown byFigs. 2, 3 sud 5 ol" ngs. The arms 7)/ oi the member B, the arms c oithe member C, und the lugs a oi the back member .fiere connected looselyor pivotally by means oi the bushings lll, the latter fitting loosely inthe lapping portions o t .id arms b c and the lugs a, as clearlyrepresented by liig. 4, 'whereby the members B C are connected looselyor pivotally with the back or supporting `nfieniber These bushings areprovided with franges or heads e, to limit the movement in one thebushings also afford bearings for wirnsls or the roller g, which is apart o a main The blade-holder is shown being shaped in cross section,and in one embodiment invention the blade-bidder is shown as consist! abasl; piece f and converging side pieces j". le-holder is provided :itits apex, or along the on inde thereof. with a longitudinal slot gf, undat one end literie-holder F is open for the iree insertion orwithdrziwsl oi the blade, or oi the auxiliary bludeholder to bepresently described. The back plate j` oi tho blade-holder is providedwith outwardly extending lugsfg, which are iitted into' lapping relationto thelugs a oi the buck or su ppoiting member A, said lu being disposedbetween the ends o the roller and the lugs a., as clearly shown by Fig.4. The roller y is provided st one end with a journal g2, which isfitted to turn freely in one of the bushings E, while in the other endoi the roller g is inserted a journal pin g3,

The memberis also provided with :i cross pin j, which is out of line with theroller I, said cross pin j being at one side oi the pivotal connection othe member B und the supporting member The pin j carries ananti-friction roller 5, showin more clearly by Fig. 5. he other member Cis 'provided with cross ,pins It ivf, a pinor guide if and another'pin37. The pine hft" and j ranged onV the member .G in a similar manner tothe pins it, t' and j 0i the member B, and pins it t and j areprovidedwith anti-friction rollers I I? and J. I i

yThe strop or strap H runs between the relier I and the, pin i at thefree end oi" the pivoted member B,

The inexnbcris furthermore provided with a v partvvay around the rollerg, between ,the latter add the blade ilder F, from whence the strop orstrap extends around the roller JT, over the roller l ot' the member C,and thence between the other roller lf and the pin if oi ssi/d member C.The strop or strap H is provided nl its ee ends with handles H, one ofwhich is clamped detuehably to an end portion oi the strop or strap by abolt H, whereby the strop or strap ,when one handle is det-sched, may beeasily run through the Ina-chine, so as to have the relation 'to themembers B C shown by Fig. 5. The strop or strap is adapted tovrun or bedrawn freely through the several parts oi the machine, and said' stropor strap is so arranged in relation to the roller g and the rollers .TIl that-it will operate on said roller g to swing the blade-holder F,and, furthermore, the ,strap so operates upon they rollersv I, '.l/ asto normally draw the members B, C toward each other, thereby tending tomaintain said members in their closed operative positions.

An iinnortant feature ',of this invention consists in the Tirovision orrnieans'or locking the members B, C, in t1 Yir open or spread positions,as shown by Fig. 2, and at the saine time locking the blade-holder F inxed relation to said opened members B, C, whereby the4 parts areprevented from slipping accidentally when introducing or withdrawing arazor blade into or from said holder l In one embodiment oi this part oiour invention, the arms bf, c, oi the members B C are provided with thelocking extensions K, K', respectively. These locking extensions areprovided at one end o the respective members B, G, and they are shapedand proportioned toengage with the respective sides oi' the bladesholderF, when the members B, C, are spread to their opened positions, asclearly shown by Fig. 2. In Connection with the locking extensions K,1li', We employ s. lever L, said lever being tule-ruined on the member'B by a pin or screw m. The lever is arranged to engage with the lockingmeniber K of the guide member C when the two members are opened, andsaid lever is held in its locking position by a spring mf. The lever Lis provided with a lug o, which is adapted to engage with the plate oithe member B, as shown by Fig. l, said lug o, tending to limit themovement of the lever under the action of the spring mf. The lever isiree to move to its locking position when the members are opened, butwhen the members' are closed and assume the position shown by Fig. 3,the locking member K of theiguide member C, engages with the lever so asto hold itin the position shown by Fig. 3.

The blade-holder F is provided with means whereby e razor blade may beforced positively into Wedging engagement witheaid holder F. Thistension or a'djusting mechanism, in one embodiment oi'our invention,consists of a yieldable member P, Whieh have shown by Fig'. 4 in theform ci; s fiat'spring. Seid Y endfot the spring member -P is providedwithsan offset or shoulder q, with which is adaptedato engage the innerend of th adjusting screw Q, the latter being mounted in a bearing orlugq of the blade-holder F said screw Q being provided with a milledhead or thumb piece q2, for its convenient operation.

We provide the machine with means for positively locking the members B Cin their closed, operative positions, and to accomplish this end, in oneform of the invention, We employ a spring latch R. Said latch isfastened to one member as C near its free end, and it is provided withan aperture lr, which is adapted to receive a stud 1", the latter beingprovided on the other member B, and arranged in the path of theprojecting portion ofthe latch R, whereby the operation I' inclusive.

v lfrom a single piece of metal. The members s s are connected pivotallytogether in a sui-.table way, such als at the end portions thereof bypins t, thus enabling *the members to be opened an'd osed as indicatedin Figs. 7, 8 and 9. The members sis/ of' the auxiliary holder arenotched at t@ and provided with two clamping*V portions u, u. Betweenthesev clamping portions ofthe members s, s, are the finger pieces t'and the clampingportion u of one member s is provided with .O peningso.The clamping portion u of the other member s has suitable studs Ir2,'thelatter being adapted to pass through the openings of a'razonblade 'ofthe Gillette type.v Some forms of ordinary safety`-razors employeJ shortblade X, of the conventional form; which is adapted to be fitted betv.eexnand to beheld by, the clamping portions il. or' the auxiliarybladeholder, as represented by Fig. 9. A double-edged v, blade Y of theGillette type may, however, be fitted -between the clamping portions lt/of the auxiliary bolder, in order that the studs 112, may pass throughthe openings in said blade Y and be received in the openings 1J of thecompanion member s. The auxiliary holder with the blade X or Y may beslipped endwise into the.- main blade-holder F, whereby the hingedlvmembers of the auxiliary holder are closed upon the .razor blade andthe parts are held .or confined in position for operation by the strapH.

Should it be desired, however, the auxiliary holder may be forcededgewise in the main blade-holder F by turningthe screw Q in orderto'bow thel spring P outwardly to the position indicated by the dottedlines vin 4, whereupon the auxiliary holder S and the blade therein areforced edgewise .within said holder This edgewise adjustment performstwo functions, first, the edge of the razor-blade may be projected a.desired distance beyond the blade-holder F, and'the auxiliary holder Sis forced into wedging engagement with the main blade-holder, wherebythe auxiliary holder` is clamped upon the safetyrazor b1adein a mannerto more 'securely hold the latter in place within the blade-holder F.

The operation of the machine may be described as follows: Assuming thatit is desired to sharpen the blade Z of an ordinary razor, the operatorproceeds to first open the machine by spreading the'guide support=- ingmembers B tothe open position shown in Fig 2. This brings the lockingmembers K, K, into engagement with.the blade-holder F, andsimultaneously the lever L is moved, by its spring mf, into engagementwith the locking member K, whereby the members B C and the blade-holderF are held firmly in their proper positions for the reception of therazor. The razor blade Z may now be moved endwise into the holder F, andthe operator then turns the screw Q so as to bow outwardly the spring landthereby force the blade Z edgewise and into clamping engagement withthe holder F. The lever L is now pressed backward by hand to theposition of Fig. Q, and the members B, C, are moved toward each other soas to be locked by the latch R into fixed relation to the blade-holder.,The machine is connected by the anchor strap D to the fix ture d, andthe handles Hf are grasped so as to draw the strop or strap H rst in onedirection, and then in the other direction. As the strop or strap isdrawn in one direction, the roller g is moved by frictional engagementwith said strop or strap, and the holder F is turned so as to presentone side of the razor edge against the strop or strap, thus sharpeningone side of the razor blade as the stropl or strapis drawn outwardly inone direction. The other end of the strop" or strap is now pulledoutwardly, and at the beginning of the operation, the roller g is atonce dra'wn so as to reverse the f position of the blade-holder vF andpresent-the other side of'the razor edge to the strop or strap. Theoperation of pulling the strop or strap-in first one direction, n andthen in the other direction, is continued indefinit'ely in order tosharpen the respective sides of the 1.00

razor edge, and each. time .the direction of the pull is changed, theholder F is reversed in position. When' the razor blade is sharpenedsuciently, theA latch R is released, the members B C are opened so as tobe locked by parts K K and the lever L, and the screw Q is turnedbackwardly to allow the spring P to return to its normal flat position,after which the blade Z may be Withdrawn easily from the holder F.

We doinot intend to limit ourselves to the employ ment of thovlatch R,for the reason that the rollers J J occupy such relation -to the lengthsof the strop or strap H andthe pivots of the members B C, as to normallyforce the said members B C to their closed positions. Under somecircumstances, therefore, we may omit the latch R,ibut we consider itpreferableto employ said latch for 1 he reason that it locks the membersB C positively in their closed positions.

When using the auxiliary blade-holder forretaining a safety-razor bladein the main holder F, it isV not essential to adjust 'the screw Q forthe purpose-of forcing 120 the auxiliary holder .and the blade edgewise,because the auxiliary holder is so proportioned that a safetyrazorblade, of whatever/type, isrcaused to extend the necessary distancebeyond the main blade holder F for the propel' operation thereon of thestrop or strap H to 125 sharpen the same. It is desirable, under somecircumstancesf' however, to adjust the screw and force the spring Poutwardly after inserting theauxiliary holder into the main holder, forthe reason that the hinged members of the auxiliary holder are forced bythe 13() sides of ,the holder F into engagement tightly with thesafety-razor blade so as to, clarnp it irnmovably within Itis quitedesirablefiu this machine to have the roll ers I l occupyproper-distances rom the blade holder F in order that the lengths of thestrap H may occupy s certain relation to the angle of the razor bladeand the holder F. Ordinarily the pins for supporting the rollers l I mayloe Iadjusted and secured in `positions for holding the rollers l lproperly to the path oi the strap, but this object may also beaccomplished by adjusting said rollers in the end ilanges of the guidesupporting members B', C. Different devices for adjusting each roller Ior 14a-re shown in Figs. l0, l1, 12 and 13.

The pin h or h is passed through transverse slots 5 in the end anges ofsaid member B or C, one end of the pin being threaded for the receptionois nut A sleeve 7 is placed loosely on the pin rand' engages et itsends with the end flanges ofthe member, thus causing the sleeve to takeup the pressure of the ond lianges when the nut/,6 is tightened. Theyroller l or l fits loosely on the sleeve-'1, and is iree 'to turnthereon when the strop is drawn over the roller.

The "pin h or h may be held in place by the nut 6, or

i if desired screws 8 may be employed for adjusting. end

locking the roller supporting pin h or h. Two screws 8, 8, may be usedat the respective ends oi the member B or C, each screw being swiveledin one oi the fixed pins oi said member so as to he held thereby fromvend- Wise movement. Said screws have threaded engagem'ent with theadjustable pin '1I orx i ofthe roller, and by Irotating one screw ortheother, or both screws, the pin and the roller thereon can be adjustedinwardly orout- .wardly with'respect to the member. Ii'desired, how#ever, short screws 9 may be fitted to the pin and work in lugs 10 whichare integral with the member.

it will be understood that either ofthe described devices may be usedfor adjusting the roller I or l', but if desired, the other rollers andguides for the strap H may be adjusted in the same manner. It ispreferred to connect the handles H, Hf pivo telly to the end portions oithe strep .tor the purpose oi per mitting the handles to roch or tilt inthe hands of the operator when pulling the strap back and forth.

Having thus described the invention, whatwe claim as new, and desire tosecure by Letters Patent iszbersland the kblade-holder, and guides forthe strop carl ried -by the aforesaid guide members, the pivots of saidguide members being out of line with guides on said members, .whereby apull on said strop exerts such frictional pressure oirthe pivots end theguide members as will keep both guide members in closed positions.
